Suspected Typos in Charles K. Alexander & Matthew N. Sadiku's Fundamentals of Electric Circuits (4th edition)

This list was prepared by Prof. Nick Reeder at Sinclair Community College, Dayton Ohio, for the 5th edition in about December of 2014. Prof. De Boer (Dordt College, Sioux Center, Iowa) has adapted it for the 4th edition by changing a few numbers to match the 4th edition and removing errata that is unique to the 5th edition.

In addition to the errors listed in the author's official list, here are typos that I [Prof. Reeder] have found in the book:

p. 10, fourth line before Section 1.5: "represented by V" should be "represented by V." (V should be in italics.)

p. 112, last line before Method 2: "-vo +1kI3" should be "-vo +1kI3." (1 should not be superscripted.)

p. 130, fifth line of Section 4.3: "known as the superposition" should be "known as the superposition principle."

p. 134, first line of Example 4.5: "use the superposition theorem" should be "use the superposition principle."

p. 143, second-to-last line: "you will not have a value for VTh" should be "VTh will have a value of 0."

p. 148, sixth line of Solution to Example 4.12: "1v / 5Ω" should be "1V / 5Ω." (V should be upper-case and non-italics.)

p. 201, Review Question 5.5: The units on all answers should µA be instead of mA.

p. 229, third line of Example 6.9: "Assume i(v)>0" should be "Assume i(0)=0."

p. 229, Answer to Practice Problem 6.9: "320 J" should be "324 J." (The given answer of 320 J would be correct if we had been asked to find the change in energy between t=0 s and t=4 s.)

p. 233, Answer to part (c) of Practice Problem 6.12: The answers are correct, but are given in the wrong order. The question asks for v1(t), v2(t), and v(t), but the answers are given in the following order: v(t), v1(t), and v2(t).

p. 319, first line: "5iR" should be "2iR." This change results in three changes to the following line: both instances of "1/5" should be "1/2," and "2/15" should be "1/3."

p. 323, fifth line after Equation (8.26): "Figure 8.9 assumes" should be "Parts (a) and (b) of Figure 8.9 assume."

p. 330, Answer to Practice Problem 8.5: "−2te−10tu(t) V" should be "−2te−10t V." For consistency with the other problems in this section, and since the problem specifies that t>0, there's no need for u(t) in the answer.

p. 336, Figure 8.20: On the graph's vertical axis, the scale marker between 20 and 30 should be 25 instead of 35.

p. 342, Equation (8.10.3): The unit should be A/s instead of V/s.

p. 347, sixth line from the bottom: "v(1) = −6.75e−1 + 0.75e−9 " should be "v(1) = −6.75e−1 + 0.75e−9 + 6." Also, on the following line, "−3.552" should be "3.552." (Delete the negative sign.)

p. 357, third line: "1/0√LC" should be "1/√LC."(Delete the 0.)

p. 375, second line: Insert the unit V at the end of the equation.

p. 424, Equation (10.6.4): "80°" should be "77.9°." Also, "10°" should be "12.1°." The first of these changes should also be made to the equation before Equation (10.6.4), and the second of these changes should also be made to the equation after Equation (10.6.4).

p. 472, Answer to Practice Problem 11.9: "177.5∠33.69° VA" should be "177.5 VA," since apparent power has no angle.

p. 477, second line: the unit at the end of the equation should be kVAR instead of kVA.
